When linking to a page on a well known wiki, you might want to use an URL abbreviation such as Oddmuse:URL Abbreviation. In this case, “Oddmuse” is the abbreviation for the longer Oddmuse URL. These abbreviations are registered on the InterMap.

You can also think of this in terms of WikiNameSpace: Every wiki on the InterMap represents a NameSpace, and the “abbreviation” is in fact a namespace qualification.

This interlink prefix is therefore variously called abbreviation, qualifier, or interlink moniker.
